Solve Round Your Results to Four Decimal Places $d x = 0.2$

Solve. Round your results to four decimal places.
-Use the Euler method with $d x = 0.2$ to estimate $y ( 2 )$ if $y ^ { \prime } = - y / x$ and $y ( 1 ) = 1$ . What is the exact value of $y ( 2 )$ ?

A) $\mathrm { y } \approx 0.1429$ , exact value is $3.0000$
B) $\mathrm { y } \approx 0.4444$ , exact value is $0.3333$
C) $\mathrm { y } \approx 0.2143$ , exact value is $1.0000$
D) $\mathrm { y } \approx 0.3571$ , exact value is $2.0000$
